--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:7546463b9f7a0b001cf61a94dcfc18f540721390 commit r10-7501-g7546463b9f7a0b001cf61a94dcfc18f540721390 Author: Peter Bergner <berg...@linux.ibm.com> Date: Wed Apr 1 14:24:07 2020 -0500 subreg: Fix PR94123, SVN r273240 causes gcc.target/powerpc/pr87507.c to fail Segher's patch that added -fsplit-wide-types-early and enabled by default for rs6000, caused pr87507.c to FAIL because when running lower-subreg earlier, we don't see any pseudo-to-pseudo copies of our wide type, which are created by combine, therefore, we skip decomposing our TImode accesses. The fix here is just to always run the third pass of lower-subreg instead of disabling it if we ran the second pass. 2020-04-01 Peter Bergner <berg...@linux.ibm.com> PR rtl-optimization/94123 * lower-subreg.c (pass_lower_subreg3::gate): Remove test for flag_split_wide_types_early.
